Template that will give you a ready-to-go project including:
- Backend project with Ktor at backend/
- Frontend project with KotlinJS and React Kotlin at web/
- Android App project with KotlinJVM at android/
- iOS App project with KotlinNative at ios/
- Shared network, domain and presentation at common/

There is a Gradle task that will produce a JAR ready to go.
$ ./gradlew stageThe output is in backend/build/libs/backend-release.jar.
The following environment variables are recognised:
| Name | Value |
|---|---|
| PORT | Port where the server will run and listen to incoming connections |
| ENVIRONMENT | Can be either production or development. If absent, will assume development. |
You can run the backend development server executing:
$ ./gradlew backend:runThis will start serving the app in port 9090 by default.
If you want to run the frontend development server, you can execute:
$ ./gradlew web:runThis will start the webpack development server in port 8080, and proxy all calls to files it doesn't know to port 9090.
If you want the frontend development server to connect to the development backend, you'll need to pass the flag -Pdebug.
$ ./gradlew web:run -PdebugWarning: The webpack development server will keep running until you execute ./gradlew web:stop.
In backend, Ktor supports hot reloading, but since the task serving the app is kept alive, you need to execute in a separate console:
$ ./gradlew backend:classes -tThis will recompilate classes on file changes, and Ktor will detect it and reload them on the next request it serves.
For the frontend, it's enough to execute the original run task with -t flag.
$ ./gradlew web:run -tOpen the root project in Android Studio or IntelliJ, and it will recognise the Android App configuration after a successful Gradle sync. You can use that configuration to run, debug and profile the app.
Open the workspace located at ios/KotlinMultiplatformTemplate.xcworkspace in XCode. The Podfile includes an entry to the common code with an extra user script for it to be recompiled as a build step.
There is a Procfile that will JustWork™️ on Heroku or Herokuish environments (think Dokku).
By default, the web bundle and a default index.html are included in the backend jar and served at /.
